Left Renal Tumor (leave + renal_tumor)
Selected AbstractsSarcomatoid collecting duct carcinoma of kidney diagnosed with urine and renal pelvic lavage cytologyDIAGNOSTIC CYTOPATHOLOGY, Issue 8 2010Akihiro Mimura C.T. Abstract A case of sarcomatoid collecting duct carcinoma (CDC) of kidney is presented, in which the diagnosis was made cytologically with voided urine and renal pelvis lavage. Cytology of hemorrhagic voided urine revealed highly atypical adenocarcinoma cells with reminiscent ductal structure, which suggested CDC as the most likely diagnosis. Computed tomography and magnetic resonance imaging demonstrated a left renal tumor, and selective lavage of left renal pelvis yielded spindle-shaped, highly atypical cells that indicated sarcomatoid carcinoma. The diagnosis of renal cancer with urine cytology is challenging because of small number of tumor cells in the urine, which are often associated with degeneration. As the urinary cytologic findings of sarcomatoid CDC have not been reported, the characteristic cytologic findings of sarcomatoid CDC are described in detail, and the differential diagnoses with diagnostic pitfalls were discussed.

[source] A case of renal mucinous tubular and spindle cell carcinomaINTERNATIONAL JOURNAL OF UROLOGY, Issue 8 2009Manabu Kato Abstract A 33-year-old man was hospitalized for treatment of a left renal tumor. The radiological findings were consistent with those of a left renal cell carcinoma (RCC). Subsequently, a radical nephrectomy was carried out. Macroscopic examination showed that a well-demarcated tumor measuring 2.9 × 2.6 × 2.5 cm was present in the middle portion of the resected kidney. The cut surface of the tumor was grayish-white in color. Pathological examination of the resected specimen showed a mucinous tubular and spindle cell carcinoma of the kidney (MTSCC-K). MTSCC-K is a low-grade renal epithelial neoplasm that has recently been recognized as a specific entity in the World Health Organization 2004 classification of RCC. To our knowledge, 17 cases of MTSCC-K in Japan have been reported by Japanese investigators. To avoid administration of excessive adjuvant treatment to patients, pathologists and urologists should consider this newly recognized low-grade malignancy when diagnosing renal tumors.

Synchronous isolated contralateral adrenal metastasis of the primary RCC is, however, very rare. Herein we report a case of RCC with a huge solitary metastasis to the contralateral adrenal gland that was surgically treated. We scheduled nephrectomy for the left primary RCC and adrenalectomy for the right adrenal tumor. However, at surgery we found a huge right adrenal tumor that had invaded the right kidney, right renal vein, and inferior vena cava. Therefore right nephrectomy was performed simultaneously with resection and reconstruction of the inferior vena cava. Pathological findings demonstrated that the left renal tumor and right adrenal tumor had the same histology. Although the patient required hemodialysis, he remains well at six months postoperatively. So far, there have been only two cases of a solitary contralateral metastatic adrenal tumor that was larger than the primary RCC, thus the present case is the third one.

We report 49-year-old man who presented symptoms of heart failure and thrombocytopenia. Computed tomography and echocardiography revealed a left renal tumor and a right ventricular mass without vena caval involvement. His symptoms progressed rapidly and he died at nine days following diagnosis of the right ventricular tumor. [source] | ||||||||||
